high CPU & Memory Utilization in Server

Hi Expert,

i've a situation which is happened on HP-UX platform and that server running on cluster handle by Data protector team.

The issue is that, server-A utilize high CPU & Memory usage but when failover the package to adoptive node, server B, the CPU & Memory usage is low. This happened for long time and affected to backup operation.

My finding is

rds consuming almost the process and i think this is normal in backup operation.

My question is

1. Did you have any idea base on below output?

2. since this server running on cluster, what kind of troubleshooting method need to perform?

3. Did clustering would be a cause? in what condition?

Additional information

Both server running on HPUX v 3 and DP was patches with latest version.
